Nemo Wilkins suddenly felt a slight dizziness, as if some invisible force had brushed through his mind, or as if he had suddenly woken up from a bizarre light sleep. In a belated awakening, he suddenly raised his head, and with a little nervousness and vigilance looked at the old gentleman who always had a gentle expression and looked elegant and harmless.

Morris gave his "informant" a friendly and polite smile in return.

However, Nemo suddenly broke out in a cold sweat. He only now recalled that from the moment he entered the secret passage, the old man's gaze had almost always stayed on him. A power that seemed to search his mind and traverse his memory was always entangled in his brain. He had been unconsciously answering every question of these uninvited guests, and even almost exposed the situation of other contact points in the city-state!

Even if these uninvited guests were holding Captain Tirian's token and knew the secret code, I shouldn't be so careless! After all, these people suddenly appeared today. According to the rules, I should test them a little more!

The drastic change in the expression on the "informant's" face certainly did not escape Vanna's eyes. She stepped forward, her expression solemn but sincere: "Mr. Wilkins, relax, we are not enemies - the tokens and codes we carry are indeed from Mr. Tirian. We just performed some tests on you for necessary safety considerations."

"Test...what test?" Nemo looked at the people in front of him with a vigilant look, "Who are you?"

"To put it simply, we suspect that a widespread cognitive pollution phenomenon has begun to spread in the city-state. This pollution can cause people to unconsciously develop false memories, lose their accurate understanding of the real world, and even become accomplices of heresy without knowing it. We cannot be sure whether the informants left by Mr. Tirian in the city are still reliable, so we can only conduct tests," Vanna explained seriously, and then changed the subject, "As for our origins...didn't you receive any news from Mr. Tirian?"

"The captain didn't explain in detail. He just said that there were a few people he could trust," Nemo answered cautiously. "Forgive my doubts - he would never make such an inexplicable arrangement before."

Morris thought about it, understood, and looked at Duncan: "Oh, maybe it's because he doesn't dare to reveal our identities without your explicit permission?"

Permission? Captain Tirian dare not reveal his identity?

Listening to Morris's words, Nemo's expression suddenly became a little strange. He subconsciously looked at the strange man in bandages and black clothes. He obviously wanted to ask something but didn't know where to start.

Duncan didn't think much about it. He just nodded slightly: "Since it has been confirmed that there is no problem with this informant, there is no need to hide it."

As he spoke, he looked at Nemo and pointed at himself: "I am Tirian's father."

The Sea Mist spy named Nemo Wilkins was silent for a few seconds, and then he suddenly glared at the captain, saying, "Don't insult the captain!"

Duncan: “…”

The atmosphere at the scene was a little awkward for a moment. Vanna and Morris couldn't help but put their hands on their foreheads. Only Alice turned her head left and right and looked around. She seemed to have no reaction and said to the informant seriously, "It's true."

Nemo obviously wanted to speak again, but before he could open his mouth this time, Morris suddenly stepped forward and patted him on the shoulder: "Young man, think about it carefully before you speak - the great 'Iron Admiral' Tirian also has a father."

Only then did Nemo Wilkins suddenly notice the subtlety in the atmosphere and come to his senses from the previous conversation. Then, he recalled the ancient legends about the Abnomer family, about Captain Tirian's family, about the Lost Homeland, and about the ghost wandering in the warp - when he looked up at Duncan again, his eyes were obviously wrong.

"I have returned from the Warp," Duncan looked at him, his voice calm, "to help Tirian deal with some trouble."

Nemo thought about it, rolled his eyes, and fell backwards.

However, Vanna next to him seemed to be prepared. Before the informant fell, she grabbed his arm with one hand, then took out a whole bottle of refreshing essential oil with the other hand, popped the stopper on the bottle and poured it directly into Nemo's nostrils.

Mr. Informant basically rushed out straight away.

"Ah...ah...A-choo! A-choo!" Nemo had completely woken up, his nose full of the strong smell of ointment. He sneezed several times before he could stop sneezing. He raised his head with snot and tears, and said nervously while sniffling, "I...I..."

"Sorry - I forgot that ordinary people's physique is worse than that of the Guardians." Vanna hid the glass bottle in her hand with some embarrassment, "But don't worry, this thing is harmless to the body."

Nemo took out a handkerchief from his pocket, wiped the tears and snot from his face while calming down. He looked at Duncan with fear and hesitation: "Is it really... it really you? Then... then what can I do for you..."

"You are serving me," Duncan waved his hand. "Don't be so nervous. Just tell me more about the situation of Frost City-State."

"Okay... okay," Nemo nodded repeatedly, and then sneezed a few more times before he calmed down. "Then what else do you want to ask?"

"Are you in touch with other informants in the city now?" Duncan asked. "How do you usually communicate? Do you gather in this sewer system, or use more covert channels?"

"We rarely gather together," Nemo said while rubbing his nose, "mainly for safety reasons - after all, many of our members are closely connected with the upper city, and they need to be more hidden. Most of the time, we exchange information through various secret channels, such as codes in newspapers, specific meeting points, or rely on some 'messenger' for single-line communication.

"In fact, even we ourselves don't know how many 'our own people' there are in the city. Most informants only know their superiors and subordinates or a few 'compatriots' in the same area as them, and the complete list is only in the hands of Captain Tirian and Mr. Aiden. I am considered the 'contact' of my level, and I have a larger list of people in my hands, but no more than ten people..."

Listening to Nemo's story, Vanna couldn't help but nodded slightly: "It's a very cautious and effective form of concealment. Most of the cultists who deal with the Guardians are not so professional."

"After all, this is a half-century business of Tirian," Duncan said casually, and then looked at Nemo, "Are you the only one stationed at this contact point?"

"There are two more," Nemo nodded, "one nicknamed 'Crow', he should be patrolling the nearby passages right now, and there's an old man who spends most of his time in the abandoned pipe squad room - even I don't know his real name, we all call him 'Old Ghost'."

Duncan exchanged glances with Vanna and Morris.

Nemo Wilkins seemed unaffected by cognitive disturbances, but others who came into contact with him might not.

"Go say hello too," Duncan nodded and said, "Where is the pipeline squad room?"

"It's right here," Nemo said, pointing his finger to the right of the fork in the road ahead. "It's where the maintenance personnel of the Second Waterway used to rest temporarily. I'll take you there."

The informant walked forward, and on the way, he began to introduce the situation of the "old ghost" to Duncan and others.

"...He is already in his seventies, almost the oldest among us. My grandfather used to work with him during the Queen's era...

"The old ghost's mind is not very clear, but he never makes mistakes when it comes to the connection between the gas pipeline and the second water pipeline. The gas pipeline we added here was built by him and his men - secretly connecting a branch from the upper main pipeline, and ensuring safety without being discovered. This is not a job that ordinary people can handle...

"The old ghost rarely goes to the surface. He spends most of his time down here. Sometimes when he drinks, he will brag to us about the past. He said that he was the engineer of the Second Waterway decades ago, and that the Queen even personally awarded him a medal at that time. But to be honest, few of his words are credible. I have also seen his medal. It is just a piece of iron with nothing on it. It is obvious that he picked it up from some corner...

"Well, he probably inhaled too much poisonous gas when he retreated to the Second Waterway. I told you about this, didn't I? Fifty years ago, when the last Queen's Guards retreated, they blocked the Second Waterway. At that time, the shaft collapsed, and some poisonous gas floated down from the upper levels. Some craftsmen loyal to the Queen went to plug the leak, and the old ghost seemed to be one of them. It is said that his mind has been abnormal since then."

"Don't mind if he suddenly starts yelling at you about something related to the Queen... He doesn't mean it."

With Nemo Wilkins chattering along the way, Duncan and others soon bypassed the fork in the road and came to a rusty iron gate near the intersection of the sewers.

Nemo went forward and knocked on the door, greeted inside, and pushed the door open: "Old ghost, a guest is coming."

As soon as he finished speaking, a hoarse but loud voice came from the door -

"Ah, the Queen is here to inspect?!"
